I obviate this objection by employing a socket-plate which may be secured to the boiler by rivets or other suitable securing devices external to the socket, the socket-plate serving to reinforce the boiler-plate at the place of connection.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a brace of the class described, the combination of a plate provided witha socket and a brace member having a paddle end and havingaballfitting in the socket of said plate.

2. In a brace of the class described, a plate having a socket and also having ways to receive securing devices in combination with a brace member having a ball fitting in the socket in said plate, and means for connecting said brace member With the structure to be braced, as set forth.

3. A socket-plate for braces,having a socket adapted vto receive a ball, also having ways adapted to receive securing devices; in combination with a brace member having a ball fitting in the socket of said plate, as set forth.

4;. Abrace member having a paddle end and a ball end; in combination with a socketplate having a socket in which the ball end threaded part of said brace member, as set forth.

6. In a device of the class described, the combination of a socket-plate having a ballsocket and ways for securing devices, a brace member having a ball fitting in the socket of said plate, securing devices securing said plate, and securing devices securing one end of said brace member, as set forth.

7 In a device of the class described, the combination of a connecting-plate attachable to the inner face of a boiler-plate, means for securing said connecting-plate, a brace member having universal connection with said connecting-plate, and means for securing one end of said brace member to a boiler-plate, as set forth.

8. In a device of the class described, the combination of a connecting-plate attachable to the inner face of a boiler-plate, witha brace member attachable to a boiler-plate, one end of said brace having universal connection with said connecting-plate, as set forth.

9. In a device of the class described, the combination of a reinforcing connecting-plate, means for securing said plate on the structure to be braced, a brace member having universal connection with said connecting-plate,and means for securing one end of said brace member to the structure against which the brace acts, as set forth.

In witness whereof I have hereunto subscribed my name at Decatur, Illinois, this 30th day of November, 1901.

HENRY E. WALLIS.
